RATCH ET- TWlSTER.

SPECIFICATION: forming part of Letters Patent No. 417,211, dated December 10, 1889.

Application filed Jam? 17, 1889- Serial No. 314,677. (No model.)

To all whom it may concern.-

Be it known that I, LIVINGSTON H. YOUR- TEE, a citizen of the United States, residing at Cairo, in the county of Alexander and State of Illinois, have invented a new and useful Device for Twisting and 'Iightening Lines, Ropes, Wires, Chains, &c., of which the following is a specification.

My invention is designed to afitord an easy and rapid method of tightening lines, ropes, wires, chains, &c., by twisting, and to supersede the use of a billet of wood commonly used for that purpose. This object is obtained by the mechanism illustrated in the accompanying drawings. The machine is preferably made of iron with wooden handles.

Figure l is an elevation of the entire machine. Figs. 2 and 3 represent vertical sections through the lines A B and O D, respectively.

E is a toothed or ratchet wheel having a slot F, the space in which is divided by a bolt or bolts of any convenient construction, also having a groove G on each side located near its periphery. 1

H II are movable jaws provided with dogs R S, to work into the teeth of the wheel E. These jaws terminate in sockets J to receive a wooden or iron handle. The jaws II Hare also provided on the inside with projecting rims I, which fit and work into the grooves G, and upon which the wheel travels. These rims conform to the shape and circle of the grooves G, and serve, when the machine is .twisted is placed in the slot alongside and on the outside of the bolt. The operation of the lever in the upper jaw causes the wheel to rotate and produces the required motion. To untwist, throw the upper dog out of the tooth of the ratchet-wheel, attach the free end of the chain to the lower dog, and raise until the teeth of the ratchet-wheel are clear, when the tension of the article twisted will untwist until slack.

Vhat I claim as my invention, and desire to secure by Letters Patent, is-

The combination of a slotted and grooved ratchet-wheel E, the slot in which is divided into equal spaces by the bolt L, with jaws H ll, provided with dogs, and having projecting rims to work into the grooves G, substantially as set forth.
